FARSTRUP BED BOTTOM, A SEAT, OR A BACK-REST Filed Sept. 6, 1960 INVENTOR YMM)Z% r ATTORNEY$ 3,068,493 BED BGTTQM, A SEAT, ()R A BAQK-REST Erik @ve Earstrnp, Eernhaneye 14, Sneirlrersten, Denmark Eiied Sept. 6, 1969, Ser. No. 53,972 Claims priority, appiieation Denmark Sept. 9, 1959 2 Claims. ((11. -191) The invention relates to a bed bottom, a seat, or a back-rest, with a stiff frame, in which the carrying members consisting of lamellae are suspended in resilient connecting links, and each carrying member consists of more than one, as a rule two, layers of non-stretchable and parallel lamellae, which are non-shiftably interconnected at the ends and at a short and constant distance from each other.

In the known constructions the centers of suspension of each carrying member are situated within the area of the carrying member and the resilient connecting links to the frame extend as a prolongation of the carrying member. This has the effect that the carrying members can adopt a strongly inclined position when lop-sidedly loaded in their transverse directions.

This non-limited possibility of inclination is a drawback when one sits down on the bed and even more when the piece of furniture is one for dual purposes, namely,

a combined piece of furniture for sitting and lying purposes.

According to the invention this drawback is remedied by the suspension points of the carrying member being at each end transferred to the sides of the carrying member area, so that the resilient connecting links to the frame are situated in the space between the carrying members in the longitudinal direction of the bed bottom.

This construction results in that each carrying member may have its separate resilient connecting links, as in the knownart, or that these links may be common to neighboring carrying members.

1n the accompanying drawing the invention is applied to abed bottom but is, of course, not restricted to this type of furniture but may be applied to any type of furniture.

PEG. 1 is a plan view of one embodiment of the bed bottom according to the invention,

H6. 2 is on a larger scale part of a modification of the bed bottom shown in FIG. 1,

PEG. 3 is a cross section along the line Ill-ill in FIG. 2, and

FIG. 4 is a similar View as that in FIG. 3 but of a somewhat modified form.

The bed bottom shown in FIG. 1 consists of a rectangular frame 6 which may be manufactured of steel tube or some other suitable material. Transversally of the frame 6 a number of carrying members 1 are stretched out. Said members are at either end secured to the frame by means of straps 4- of a resilient material, e.g. rubber straps.

Each of the carrying members consists of two or more parallel lamellae of non-stretchable material Which are non-shiftably interconnected through spacing members 2 at their ends. As'examples of suitable lamcllae may be mentioned wooden lamellae or metal lamellae. The spacing members 2 which may be secured'to the lamellae by glueing or Welding, as assumed in the embodiment shown, or in other suitable manner such as by rivets or.

3,%8,493 Patented Eec. 18, 1962 the like, protrude laterally from the lamellae so that bars or pegs 3 are provided for suspending the carrying members by means of ring-shaped rubber straps 4.

in F168. 2 and 3 each carrying member consists of an upper lamella 1, and a lower lamella 7, and at each end a spacing member 2 which is situated transversely of the two lamellae, and with the bars or pegs 3 which project that far out on either side of these lamellae as to divide the space between the carrying members. The rubber straps d which as endless rings are situated in the space between the carrying members are common to and encircle the free ends of the spacing members protruding into this space and belonging to two neighbouring carrying members, and the upper part of a stirrup 5 which is secured in the frame 6 which is of wood. As shown to the left in FIG. 2 a strap need not be in one piece but may be in two pieces 4a and 411, one for each of the two neighbouring carrying members. If desired, some of the straps, e.g. every second, may be in one piece and the other in two pieces, or all of them may be in two pieces.

PEG. 4 shows part of a bed bottom where the long side 10 of the frame is of steel tube having a longitudinal impression 11 for holding the stirrups 5 in correct position.

The embodiment shown for the carrying member is hardy and cheap in mass production.

The resilient connecting links for the suspending of the carrying members in the frame need not be of rubber, but may also e.g. be a flat spring of steel.

I claim:

1. A resilient bottom for pieces of furniture of the kind comprising beds, seats and back-rests, said bottom comprising an open polygonal frame, carrying members resiliently suspended between opposite sides of said frame, each of said carrying members comprising two nonstretchable lamellae, spacing means connected in a nonshiftable manner to the ends of said two lamellae, said carrying members being provided at their ends with two opposite lateral projections, and resilient members con-,

necting such projections to the adjacent side of said frame.

2. A resilient bottom for pieces of furniture of the kind comprising beds, seats and back-rests, said bottom comprising an open polygonal frame, carrying members resiliently suspended between opposite sides of said frame, each of said carrying members comprising two nonstretchable lamellae, spacing means connected in a nonshiftable manner to the ends of said two lamellae, said carrying members being provided at their ends with two opposite lateral projections, adjacent projections of two adjacent carrying members constituting a pair, and a resilient strap connecting each such pair to the adjacent side of said frame.
